SPECIFICATION forming part of Letters Patent No. 543,291, dated July 23, 1 895.

Application filed April 16, 1895. Serial No. 545,885. (No model.)

To all whom, it may concern:

Be it known that we, JAMES A; CARROLL and WVI-LLIAM BROOKS, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Stoves, of which the following'is a full, clear, and exact description.

Our invention relates to an improvement in direct-draft stoves; and the object of the invention is to provide for an economy in fuel and to secure a maximum of heat from a given amount of fuel; furthermore, to provide a means whereby a direct-draft stove may be used as a single or as a double heater; and another object of the invention is, instead of opening the fire-door in direct-draftstoves in order to cool the same, to provide a means for reducing and controlling the'fire without danger of gas escaping into the room and at the same time to afford a complete circulation of air over the body of the'fire.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in both the views.

Figure 1 is a longitudinal vertical section through a direct-draft stove having the improvements applied thereto, and Fig. 2 is a side elevation of a top particularly adapted for said stove.

In carrying out the invention the stove A may be of any direct-draft type, that shown in the drawings being the ordinary cylinder stove, and at the back of the stove an air-supply chute B is located, being fitted closely to the stove and extending down to the floor, the end portionof said chute being open, Whereby a chamber 10 is provided to conduct cold portion of the stove, being'over the fire-pot,

and thebottom 11 of this drum or radiator is beveled from the front downwardly and rearwardly, and the drum or radiator at itsbottom portion is provided with a neck 11 which extends outward through the back of the stove within the chamber of the air-chute B, as is best shown in Fig. 1. Preferably a cap-ring C is placed upon the top of the stove and the upper end of the radiator or drum is fitted in the said cap-ring in any suitable or approved manner. 1

Thelsmoke-pipe 13 is given an elbow shape where it connects with the collar 10 of the stove, and in this pipe at or near said collar a damper 1A is located, being made 'to fit closely and snugly in the pipe when the damper is closed, so as to preventthe exit of hot air, directly through the smoke-pipe, and this damper may be made of anyapproved material and provided with a packing of asbestos or equivalent material.

A gas-escape pipe 15 is made to pass through the lower portion of the drum or radiator 0, one end of the said gas-escape pipe passing out through the radiator immediately back of the fire-door 17 of the stove, while the opposite end of the gas-escape pipe is. carried through the cold-air-supply chuteB and into the smoke-pipe 13 back of the damper 14; and I the exitof the gases and waste products of combustion through the gas-escape pipe may be controlled by inserting nipples 16 of any desired size into the exit end of the gas-escape pipe to regulate the opening at that point.

When the stove is to be used for heating a room or rooms on the same floor, the open top 18 is fitted over the upper end of the radiator or drum 0, and in this event the top is preferably made as shown in Fig. 2, consisting of a coil of stout wire suitably ornamented, in

order that the air passing from the bottom of the 'room up through the air-supply chute B and into the drum or radiator 0 may find an exit in a heated state into the room through the openings in the top 18; but if in practice it is found desirable to heat a room on an upper floor, all that is necessary is to remove the top 18 and introduce one end of the pipe- It is evident that in this form of stove the cold air is taken from the floor. It is carried up into the drum or radiator, heated and delivered therefrom without passing over or in contact with the fuel, and also itis evident that the damper 14 may be completely closed and the fire will still burn slowly and uniformly by reason of the gases and waste products of cumbustion passing off into the flue through the escape-pipe 15, the rapidity with which the exit is made being regulated by the reduced nipple 16 placed in the delivery end of the gas-escape pipe. Again, it is evident that there is no necessity whatever of opening the fire-door in order to cool the fire; therefore there will be no possibility of persons in the room. with the stove being subjected to the influence of escaping gases.

Havingthus described our invention, we claim as new and desire to secure by Letters Patent 1..In a stove, a drum, a cold air supply therefor, and a gas escape pipe extending through the drum from side to side and communicating with a smoke flue as and for the purpose set forth.

2. In a stove of the character described, a drum located above the bed of the fire and provided with an extension extending through the outside of the stove, a cold air supply trough communicating with the said drum, a smoke pipe, adamper located therein capable of entirely closing the said pipe, and a gas escape fine leading transversely through the drum and communicating with the smoke pipe as and for the purpose specified.

3. In a stove, a drum, a radiator secured in the said drum above the fire pot, a cold air supply trough or chamber connected with the said drum, a smoke pipe provided with a damper capable of closing the same, and a gas escape pipe extending transversely through and entirely across the drum and communicating with the said smoke pipe, as and for the purpose specified.

4. In a stove, a drum held over the fire pit thereof, having communication with the outside, a cold air supply chamber in communication with the said drum, and a gas escape pipe passing through the drum and through the cold air chamber and communicating with the flue at its outer end, as and for the purpose set forth.

5. In a stove, a drum held over the'fire pit thereof, having communication with the outside, a cold air supply chamber in communication with the said drum, and a gas escape pipe passing through the drum and communicating with the flue at its outer end and provided with adjustable reducing devices at its outlet end, as and for the purpose specified.

6. The combination, with a stove, a drum suspended therein over the fire pot and communicating with the exterior, a cold air chute communicating with the said drum, a smoke pipe located above the receiving end of the drum and provided with a damper capable of closing the same, and a gas escape pipe extending from the forward portion of the drum through the drum and into the said smoke pipe at the rear of its damper, as and for the purpose specified.

7. The combination with a stove, of an air heating drum suspended therein above the fire chamber, and having its lower wall inclined downward and rearward from the side adjacent to the stove door, an air fiue communicating with the interior of the drum, a smoke flue communicating with the interior of the stove, a damper in the smoke fiue and a gas escape pipe extending entirely across the lower portion of the drum and having its inlet adjacent to the stove door and its outlet in the smoke flue as and for the purpose specified.

8. In a stove, the combination with an air heating drum suspended therein, of an open top piece therefor consisting of a metal rod or bar extended spirally upward, as and for the purpose specified.
